PHOTOPLATE-HOLDER.

a I Specification of Letters Patent.

Patented March 5, 1907.

Application filed Augus 8, 1905. Serial No. 273,258.

To aZZ whom it may concern:

Be it known that I, JOHN R. citizen of the United States, residing atReadstown, in the county of Vernon, State of Wisconsin, have inventedcertain new and useful Improvements in PhotoplateHolders; and I dohereby declare the following to be a full, clear, and eXact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to cameras, and more particularly toplate-holders therefor, and has for its object to provide a holderarranged for the reception of supplemental holders of different sizes,the holder being adapted for easy and quick adjustment to receive thedifferent supplemental holders.

Other objects and advantages will be apparent from the followingspecification, which describes an embodiment of the present invention.

In the drawings, forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a front elevation of the present holder with the slideremoved and showing a supplemental holder in position. Fig. 2 is asection on line 2 2 of Fig. 1, the slide being in position. Fig. 3 is alongitudinal section through the slide and adjacent parts. Fig. 4 is adetail view of the slidegrip in perspective. Fig. 5 is a longitudinalsection, the slide being partly withdrawn.

Referring now to the drawings, the present invention comprises arectangular frame 5, having a back 6 and transversely-eXtendingsupporting-plates 7. Upon the forward face of each of these plates 7there are pivoted a pair of plates 8, the outer end portions of whichare rounded, as shown 'at 9, these rounded portions being directedtoward each other and being provided with intermeshing gear-teeth 10, sothat movement of one of the plates 8 upon its pivot results in similarmovement of the other plate 8 of the same pair.

Strap-springs 11 are secured to the end pieces 12 of the frame 5 at oneend and have their other ends engaged in notches 13 in the outer sideedges 14 of the plates 8, the arrangement of these springs 11 being suchthat the plates are held with the outer ends of their areuate portions 9in engagement with the end pieces 12 of the frame, the inner ends of theplates thus lying'at the limits of GARLICK, a their movements towardeach other.

'lhe plates 8 carry arms 14 at their inner ends, which when the plates 8are in their normal positions extend toward the center of the frame,though it will be understood that when these plates are moved againstthe action of the springs 11 the arms will be moved away from eachother. Each of the arms carries a forwardly-extending pin 15 at its freeend, these pins having heads 16, as shown, and it will be seen thatthese pins occupy the corners of a rectangle, so that a supplementalplate-holder 17 may be disposed in position for engagement by the pins,which will hold the plate-holder 17 at the center of the frame 5. Itwill also be apparent that the pins 15 may be separated or permitted tomove toward each other to receive and hold plate-folders of differentsizes.

The frame 5 is grooved, as shown at 18, for the reception of a slide 19of peculiar con struction. These grooves 18 lie adjacent to the forwardopen side of the frame, and at one end of the frame the end piece 12adjacent to the forward side thereof has an opening 22 thercthrough,with which the grooves 18 communicate and through which the slide 19moves.

The slide 19 consists of a body portion 23, which is hollow and which isopen at its inner end, as shown at 2 1, and at the outer end of theslide there are attached thereto guides 25. The body portion of theslide is composed of front and rear plates 26 and 27, respectively,which are held in spaced relation to each other by means of strips 28,secured between the plates at the edges thereof, these strips at theirouter ends having rearwardl extending enlargements 30 and being curvedat their outer ends, as shown at 29. The forward plate 26 of the slideis curved rearwardly around the curve d ends 29 of the strips and issecured to the rearward edges of the enlargements 30, so that thepassage 24 between the plates has a return portion 31, extending towardthe free end of the slide. The guides are secured to the extensions 30and communicate at their outer ends with the return portion 31 of thepassage for the reception of a curtain 32, movable upon a roller 33,journaled betwen the outer ends of the strips 28 and extendingtransversely of the slide. The guides 25 are slidably engaged inpassages 341, formed in the end portion 12 of the frame, and when theslide is moved inwardly these guides slide into the holder.

The curtain 32 has at its inner end a grip 35, adapted for engagementwith the slide 36 l of the supplemental plateholder 17, engaged by thepins 15, and it will be apparent that the curtain 32, having, as itdoes, a fingerpiece 38 at its outer end, may be grasped by thisfinger-piece to move the curtain into the I guides 25, thus bringing thegrip 35 and a slide engaged thereby into the space between the plates 26and 27 of the slide 19.

The grip 35 consists of two pivotally-connected jaws 38 and 39,respectively, and eX- l ten ding inwardly from the strips 28 at theinnor ends of these strips there are pins 40, which are so disposed thatthey enter between flanges Y and Z at the ends of the jaws 38 and l 39when the grip is moved inwardly with the curtain 32 to separate thesejaws for the rel ception of the slide 36 therebetween, and l when thecurtain is moved to move the grip outwardly a spring 41 brings the jawstogether, they having moved out of engagement with the pins to grip theslide.

It will thus be seen that in use a plateholder may be disposed withinthe pins 15, the slide 36 of this plate-holder being in operativeposition and the slide 19 being withdrawn to expose the plate-holder.The frame 5 is then disposed in the camera, and the curtain is moved toopen the grip 35. The slide is then moved to bring the jaws 38 and 39into position to engage the slide 36, after which the curtain is movedto disengage the jaws from. the pins 40, which permits the jaws toengage the slide, when the slide may be withdrawn and picture may betaken. It will be understood that the jaws are disengaged from the pinsbefore they are moved out of position to engage the finger-piece of theslide 36, so that they grip the latter.

It will be seen that the adjacent end 12 of the frame limits themovement of the outer end of the curtain, and the arrangement is suchthat this limitation prevents entire removal of the slide 36 from theplateholder, so that the slide may be returned to operative position bymoving the finger-piece 38 of the curtain away from the frame.

It will be seen that the slide 19 may be moved inwardly to bring thegrip 35 into position to engage the slide of the supplementalplate-holder, should this plate-holder be small, and it will also beapparent that this movement of the slide brings the outer end of thecurtain nearer to the frame to reduce the possible movement of thecurtain, thus preventing the withdrawal of the slide from theplateholder, as described above.

If the present device is to be used as a plate-holder, the plate beingengaged within the pins 15, the slide 19 is used as is the usualplate-holder slide, as will be readily underl stood. l
